There has been great interest in the use of carbon nano-materials (CNMs) in agriculture. However, the existing literature reveals mixed effects from CNM exposure on plants, ranging from enhanced crop yield to acute cytotoxicity and genetic alteration. These seemingly inconsistent research-outcomes, taken with the current technological limitations for in situ CNM detection, present significant h...

Plant protection based on novel alternative strategies is a major concern in agriculture to sustain pest management. The marc extract of red grape cultivars reveals plant defence inducer properties. Treatment with grape marc extract efficiently induced hypersensitive reaction-like lesions with cell death evidenced by Evans Blue staining of tobacco leaves. Examination of the infiltration zone an...

Since the early 1980s, American taxpayers have invested heavily in public, university, and small business developers of crops and foods improved using biotechnology. Yet the return on this investment, in terms of new, improved genetically engineered (GE) crops, is disappointingly thin. Although the U.S. Department of Agriculture, universities, and small businesses have developed dozens of GE cr...

Introduction Raising and selling frogs on a commercial basis has not proven to be successful economically in Virginia or elsewhere in the United States to our knowledge. Although farming for frog legs sounds promising, operating a profitable frog farm seems to be more of a myth than a reality. Those few individuals who claim to be successful frog farmers generally are distributors engaged in th...

The paper focuses on conservation agriculture (CA), defined as minimal soil disturbance (no-till, NT) and permanent soil cover (mulch) combined with rotations, as a more sustainable cultivation system for the future. Cultivation and tillage play an important role in agriculture. The benefits of tillage in agriculture are explored before introducing conservation tillage (CT), a practice that was...

Conventional agriculture has improved in crop yield but at large costs to the environment, particularly off-site pollution from mineral N fertilizers. In response to environmental concerns, organic agriculture has become an increasingly popular option. One component of organic agriculture that remains in question is whether it can reduce agricultural N losses to groundwater and the atmosphere r...

it has been proven that polyolefins specially low density polyethylene (ldpe), are resistant against degradation and microorganism attacks; thus, one of the most important properties of industrial plastics, is their environmental biodegradability. since plastics are being widely used in agriculture, horticulture and packaging, meeting this requirement becomes increasingly dificult (specially in...
